No Standard Roles SAP_XI_B2B Visible on PO System

Hi,

I can see that B2B relevant components been installed in our PO System.

But when try to access the b2bic via link http://host:port/b2bic to my surprise ended up with 404 error.

Later when I checked the standard roles SAP_XI_B2B* I could not find the same in our system.

I even check the configuration guide if there are any manual steps and got missed out...but couldnot find any...

What could be reason for this ? Any Advices on this.

Thanks in Advance

Rajesh
